A novel N,N,N-trimethyl-[1,1'-biphenyl]-2-methanaminium compound is subjected to a rearrangement reaction to give a 3-dimethylaminomethyl-2-methyl-[1,1'-biphenyl] compound which is then converted to the corresponding 3-halomethyl-2-methyl-[1,1'-biphenyl] compound. The halomethyl compound is an intermediate for pyrethroid and related insecticides having the alcohol moiety derived from a 2-methyl-[1,1'-biphenyl]-3-methanol.
一种新型的N,N,N-三甲基-[1,1'-联苯]-2-甲胺盐化合物经过重排反应得到一种3-二甲氨甲基-2-甲基-[1,1'-联苯]化合物,然后转化为相应的3-卤甲基-2-甲基-[1,1'-联苯]化合物。卤甲基化合物是拟除虫剂和相关杀虫剂的中间体,其中醇基来源于2-甲基-[1,1'-联苯]-3-甲醇。
